Description

Prevents priority inversion by limiting how many low-priority event
callbacks can be invoked before checking for more high-priority events.

Note:

Available since
libevent 2.1.0-alpha
.

Parameters

max_interval

An interval after which Libevent should stop running callbacks and check
for more events, or
0
, if there should be no such interval.

max_callbacks

A number of callbacks after which Libevent should stop running callbacks
and check for more events, or
-1
, if there should be no such limit.

min_priority

A priority below which
max_interval
and
max_callbacks
should not be enforced. If this is set to
0
, they are enforced for events of every priority; if it's set to
1
, they're enforced for events of priority
1
and above, and so on.
